According to the S-1 filing, Optiv hopes to raise around $100 million in funding, although it did not say how many shares it planned to sell or at what price. It said it hopes to put the financing toward investments in “short-term demand deposits at various financial institutions,” general corporate purposes, and to pay down its significant debt, which totaled $651.8 million at the end of September.

Optiv has continued to expand since its merger, unveiling the acquisitions of identity and access management company Advancive in April, third-party risk application company Evantix in May, and New England security solution provider Adaptive Communications in June.

According to the S-1 filing, Optiv had sales of $643.8 million for the nine months ending Sept. 30, a drop of 1 percent year over year. The company has seen dropping security technology revenue, down 8 percent year over year to $490.3 million, and rising services sales, up 30 percent year over year to $153.4 million. Optiv reported a loss of $5.7 million on those sales, compared with a loss of $13.6 million in the same period the year before.

For the full year last year, Optiv reported revenue of $947.3 million, up 134 percent year over year, with a 136 percent increase in its security technology business to $783 million and a 126 percent increase in its security services business to $164.3 million. It reported a loss of $14.4 million on those 2015 sales.

It has been a relatively slow year overall when it comes to tech IPOs, although some other security companies have also filed for their initial public offerings. Dell SecureWorks, an Optiv competitor, filed for its IPO in April, launching into the public market later that month.
